i have found that this thing has more mood swings than a woman. ive got a 427 wtih flat tops 291 heads not sure on cam size air gap intake 850 mighty demon msd street fire distributor i believe a holley red pump,cell with half inch aluminum line front to back with regualtor, pressures carries 7-7.5. when it runs it runs great. At times i can drive it with no problems other times it seems to be flooding or running out of fuel. while cruising doesnt matter at what speed,if you try to gain speed with a little pedal push it wants to spudder like its running out of fuel but if you crack it wide open it will try to pick up and run and it doesnt do it all the time.. Can anyone help before i accidentley leave these monster on the rail road tracks???
